Answer:
(7, -2.4). (3,8,1) = 9
The vectors are not perpendicular
Step-by-step explanation:
The inner product between two vectors A = {a, b, c} and B = {d, e, h} is:
In this case the vectors are (7, -2,4) and (3,8,1). Then the product point is:
The dot product between two vectors is equal to zero only if the vectors are perpendicular to each other.
In this case the dot product is nonzero, therefore the vectors are not perpendicular
Let number of wizards in the magic club = x . And number of goblins is 20% more than that of wizards.
Therefore , number of wizards in the magic club is
And total number of goblins and wizards = 120
Therefore , we will get
Multiplying both sides by 100
Dividing both sides by 220
Therefore number of goblins

To figure this out you would have to multiply 40 by 2 since the first problem is 10 and the next is 20. So the answer would be 80.
Answer:
74.8 cm^2
Step-by-step explanation:
The figure is a parallelogram with base of 11cm and height of 6.8cm . To find the area, we multiply the base by the height to get 11 × 6.8 = 74.8 cm^2
